Selecting UVs

Much like the 3D Viewport, the UV Editor has selection mode buttons in the header, as well as a Select menu.

Sync Selection(選択を同期)

When enabled (the default), the UV Editor and 3D Viewport share a synchronized selection state. Selecting components (vertices, edges, or faces) in one editor will automatically select the corresponding elements in the other.

With Sync Selection enabled, all faces are visible in the UV Editor at all times. Selecting a vertex, edge, or face in the 3D Viewport selects its corresponding UV elements. However, when a single 3D vertex or edge corresponds to multiple UV vertices or edges (for example, along a UV seam), you cannot select them individually—selecting one selects all of them.

When disabled, only the UVs belonging to the currently selected faces in the 3D Viewport are shown. Selections in the UV Editor are independent, allowing individual UV vertices and edges to be selected even if they correspond to the same mesh vertex or edge. Selecting in one editor no longer affects the other.

注釈

Currently, only some 3D Viewport selection operations preserve per-UV selection data, including basic picking, box, circle, and lasso selection. Other operators, such as Select Random or Select Similar, will reset the stored UV selection, causing all UVs connected to selected mesh elements to become selected. Support for additional operators may be added later.

ヒント

Internally, UV selection data is stored per face corner and created on demand to avoid overhead. Python scripts that modify mesh selections can use the API functions to synchronize or clear the UV selection state as needed.

Selection Mode(選択モード)

Vertex(頂点):

1 Select vertices.

Edge(辺):

2 Select edges.

Face(面):

3 Select faces.

If Sync Selection is enabled, you can hold Shift while clicking a selection mode to activate multiple ones at the same time, or Ctrl to expand/contract the selection.

Mode(モード):

Edit Mode(編集モード)

Menu(メニュー):

Header ‣ UV Island Selection

ショートカットキー:

4

Select contiguous groups of faces that are connected in the UV map.

Sticky Selection Mode(吸着選択モード)

Options for automatically selecting additional UV vertices. Only available for Face select mode or if Sync Selection is disabled.

Disabled(無効)

Each UV vertex can be selected independently of the others.

Shared Location(同じ位置)

Automatically select UV vertices that correspond to the same mesh vertex and have the same UV coordinates. This is the default and gives the illusion that multiple faces in a UV map can share the same vertex; in reality, they have separate vertices that overlap.

Shared Vertex(共有する頂点)

Automatically select UV vertices that correspond to the same mesh vertex, even if they have different UV coordinates. This is also the behavior when Sync Selection is enabled.

Select(選択) メニュー

All(すべて) A

Selects all UV elements.

None(なし) Alt-A

Deselects all UV elements.

Invert(反転) Ctrl-I

現在の選択状態を反転します。

Box Select Alt-B

See Box Select.

Box Select Pinned(ボックス選択 (ピン)) Ctrl-B

Like Box Select, but only selects pinned UV vertices.

Circle Select(サークル選択)

See Circle Select.

Lasso Select(投げ縄選択)

See Lasso Select.

More(拡大)/Less(縮小) Ctrl-NumpadPlus, Ctrl-NumpadMinus

Expands/contracts the selection to/from the adjacent elements.

Select Similar Shift-G

Selects UV elements that are similar to the active one in some way. The Adjust Last Operation(最後の操作を調整) panel provides several options:

Type(タイプ)

The property to compare. Which properties are available depends on the Selection Mode.

Vertex Selection Mode

Pinned:

Selects vertices with the same pinned state.

Edge Selection Mode

Length(長さ):

Selects edges with a similar length in the UV map.

Length 3D:

Selects edges with a similar length in the 3D mesh.

Pinned:

Selects edges with the same pinned state.

Face Selection Mode

Area(エリア):

Selects faces with a similar area in the UV map.

Area 3D:

Selects faces with a similar area in the 3D mesh.

Material(マテリアル):

Selects faces that have the same Material.

Object(オブジェクト):

Selects faces that belong to the same object. This is useful when multiple objects are in Edit mode at once.

Polygon Sides(ポリゴンサイド):

Selects faces with a similar number of edges.

Winding:

Select faces that have the same orientation (facing upwards or downwards in the UV map).

Island Selection Mode

Area(エリア):

Selects islands with a similar area in the UV map.

Area 3D:

Selects islands with a similar area in the 3D mesh.

Amount of Faces in Island:

Selects islands with a similar number of faces.

Compare(比較)

The comparison operator.

Equal:

Select elements whose value is equal.

Greater:

Select elements whose value is greater or equal.

Less(縮小):

Select elements whose value is less or equal.

Threshold(しきい値)

Tolerance for values that are almost, but not quite the same. A higher threshold will select more elements.

Select Linked(リンク選択)

Linked(リンク) Ctrl-L

Selects all elements that are connected to the currently selected ones.

Shortest Path(最短パス選択)

Selects the path between two selected elements. (See below)

Select Pinned(ピン止め頂点を選択) Shift-P

Selects all pinned UVs.

Select Split(分離部分を選択) Y

"Detaches" the selected faces so they can be moved elsewhere without affecting their neighbors.

ヒント

Unlike Split Selection for meshes, which physically disconnects faces, this is a pure selection operator. In UV space, the faces were never connected to begin with; it only seemed that way because Sticky Selection automatically selected the vertices of the neighboring faces. Select Split deselects those vertices again.

As an alternative to Select Split, you can set the Sticky Selection Mode to Disabled.

Select Overlap(重複部分を選択)

Selects all UV faces that overlap each other.

Shortest Path(最短パス選択)

参照

Mode(モード):

Edit Mode(編集モード)

Menu(メニュー):

Select(選択) ‣ Select Linked(リンク選択) ‣ Shortest Path(最短パス選択)

ショートカットキー:

Ctrl-LMB

Selects all the UV elements along the shortest path between two elements: the two selected elements when activated using the menu, or the active one and the clicked one when activated using the shortcut.

Face Stepping(飛ばして面選択)

For vertices: allows the path to step across faces, following their diagonal rather than their edges.

For edges: selects disconnected edges that are perpendicular to the path (edge ring), rather than connected edges along the path (edge loop).

For faces: allows the path to go through faces that only share a vertex, rather than an edge.

Topology Distance

Calculates the distance by simply counting edges rather than measuring their lengths.

Fill Region(領域をフィル) Shift-Ctrl-LMB

Selects all shortest paths (rather than just one).

Dashed Line Options

Allows to only select elements at regular intervals, creating a "dashed line" rather than a continuous one.

Deselected(選択解除)

反復で選択解除された要素の数。

Selected(選択)

反復で選択された要素の数。

Offset(オフセット)

The number of elements to offset the sequence by.

Select Edge Loop

Mode(モード):

Edit Mode(編集モード)

ショートカットキー:

Alt-LMB, or Shift-Alt-LMB for extending the existing selection.

Holding Alt while clicking an edge selects that edge and then expands the selection as far as possible in the two directions parallel to it. (While this of course works for selecting edge "loops" that go all the way around a mesh, it also works if there's no loop.)

You can additionally hold Shift to extend the current selection rather than replacing it.
